Shell launched a competition called Ecomarathon (Eco-marathon).
Ecomarathon is about driving technology innovation for improved energy efficiency. The Shell Eco-marathon challenges students around the world to design, build, and test vehicles that travel further using less energy. See this video for more details
A little history
The Shell Eco-marathon began in 1939 at a Shell research laboratory in the U.S. as a friendly wager between scientists to see who could get the most miles per gallon from their vehicles. From these humble origins, the organized competition for fuel economy evolved and moved to Europe. The Shell Eco-marathon in its current form began in 1985 in France, attracting thousands of young engineers and scientists from 20 European countries. The Shell Eco-marathon Americas was first held at the California Speedway in 2007.
The vehicles may use one of the following fuel or energy types:
- Shell Unleaded 95 (EU) / Shell Plus 89 (US) Petrol/Gasoline
- Shell Diesel
- Liquefied Petroleum Gas (LPG)
- Shell Gas To Liquid (100% GTL)
- Fatty Acid Methyl Ester (100% FAME)
- Ethanol E100 (100% Ethanol)
The complete list of rules can be found on Shell website. So if you know how to build fuel saving gadgets this competition may be good for you.
